Hey, guys, I have an in-ground pool at home which was built by some in-ground pool builders from toronto ( Swimming Pool Builders Contractors Toronto | Solda Pools ). I never use the pool much and I am thinking of converting it into a pond. I have already bought some fishes like comet, koi carps and rossette's. I am thinking of buying more once the pond is settled and ready to go. I have heard that you need to get a good filter system. I have already got it so I can check that out of my list. Is there anything else that I need to look at? Any tips on this would be great.
